SEVEN NEW WHITE-WINGED DOVES 



19 



Panama must have been a cage bird; indeed its appearance suggests 

 its having been kept in confinement." This adult male has its primaries 

 and rectrices moderately worn, but no more so than many other 

 breeding white-winged doves. Nothing about the appearance of this 

 specimen indicates that it had been caged; its plumage is not soiled, 

 nor are feathers broken or fault-barred. The date, May 20, 1889, was 

 within the breeding season. It is comparable in size and color to 

 specimens of collina from the Pacific coast and piedmont from Guate- 

 mala to Costa Rica. According to Alexander Wetmore, with whom 

 this specimen was discussed, the collectors Heyde and Lux obtained 

 a large number of "trade skins," many of them from Guatemala. 

 There are several instances in which Guatemalan birds in their col- 

 lections were mislabeled "Panama." For the present it seems inadvis- 

 able to accept this specimen as proof that collina occurs there. 

 Collina breeds and wimters as far south as the Guanacaste region 

 of Costa Rica, so a few of them may have populated arid woodlands of 

 southwestern Panama, but if so it is strange that no specimens of 

 this race have been collected or reported there since 1889.

Only 11 specimens of white-winged doves from Panama were avail- 

 ible for this study. A twelfth specimen was not sufficiently authenti- 

 :ated to be considered a satisfactory record. The 11 birds were from 

 the coastal mangrove swamps of southwestern Panama, and eight of 

 the nine males were collected during the breeding season. They are 

 different from other resident populations farther north in Central 

 A^merica and are described as a distinct subspecies which may be called:
